APPARATUS.

To all whom it may concern:

Be it known that I, JAMES N. MrrennLL, a citizen of the United States, residing uti Washin'gton city, in the District: of Cohuu- 5 bis, have invented certain new and useful Improvements in Disinfccting i-rpparatus. of which the following is a specification.

This invention relates to disinfecting apparatus; and the object of the invention is to provide a simple and improved apparatus which'inuy be used in connection with a flushing tank of ordii'iar'y construction for the purpose of supplying a charge of disinfecting liquid whenever the flushing tank is operated; the disinfecting liquid being discharged directly into the water used for flushing urposes for admixture therewith. A furt 1er object of the invention is to provide asiniple and improved construction whereby the improved apparatus is auto matically actuated to deliver a charge of disinfectant whcnevetuthe flushing tank, in connection with which it is used, is operated. Still further objects of the invention are to simplify and improve the construction and operation of this class of devices; and with these and other ends in view which will readily appear as the nature of the-invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the drawing Figure 1 is a side elevation of a disinfecting apparatus constructed in accordance with the invention. Fig. 2 a top Ian view of the same. Fig. 3 is a vertlca sectional view taken on the plane indictated by the line 3-3,in Fig. 2. FigAise perspective detail view showing one end of the pivoted tubular member which is used for discharging the disinfectant. Fig. 5 is a front elevation of the apparatus.

Coiresponding )arts of the several figures are denoted by 1i e characters of reference.

The improved apparatus comprises a receptaci'e or reservoir 1 which may be of any desire shape and dimensions; preferably howev'er, it is made approximately L-shapcd, in plan, f r the reason that a vessel of this configuration may be readily acconunodated in one corner of an ordinary flushing tank, without obstructing or interfering with the mechanism of such tank. The side walls 2. 2- of the vessel 1, which are disposed at right.

angles to ouch other, ure provided near the upper cdge'ot' the \cssel with hook shaped lugs Z). 25, adapted to engage over the upper edge of :1 l'lushiru; tank, upon which the vessci 'i may thus he suspriuled in position for opm'ation. The top of the vessel 1 is formed with a filling aperture surrounded by a neck or thing-o i having; it screw cap .7.

()uo ot' the Murrow end walls of the vessel 1 which is preferably inclined and curved to form a sent "for the discharge pipe 8, shown at'o, is provided with a slot. or aperture 7 adjacent to v-shiz-h the discharge pipe or tube 6 pivotally supported; suld tube being provided with ours or lugs, as shown at 9, for the passage ol n trunsv 'soly dispose pivotal pin or sup uu-tiug member 10. The inner end oi the tube 5, which projects into the vessel 1, is bent dmvuwurd, its shown at; it, and said tube 't'urthc-r hunt to form an upproximately horizontally disposed terminal portioi'i constituting u NOOP 12 which may normally r t upon the bottom of the vessel 1, and which is provirjled with a terminal upturned lip .t 3 LHUIHJQI'It to the aperture 14. It will be readily s on, by reference to Fig. 3, that when the (.li ;.harge tube occupies its normal position, with the scoop 12- rosting upon the bottom of the vessel 1., the liquid contents of said vessel will enter through the uperturc 1 11 and rise within the tube; when the latter is tilted, the scoop 12 will be elevated to :1 position above the level or the fulcrum or pivotal supporting point of the tube, and :1 portion oi? the liquid will be discharged through the outer end of said tube.

The tube is ]').l'OVltlt.li with ours or lugs, l()\\'[i at. if) serving to pivotully support a rod to carrying at its lower extremity a.

.17 which is provided with :1 l'u'ncket 18 an aperture 19 our ring a guide rod 20 which is suitably tfOltl'. rtod with and exteuds tloivi'iivnr lly from tho bottom of the vessel l.

The parts are lo he so proportioned, that when the vessel 1 is suspended or supported in position in an ordinary Hus-hing tank, at one of the upper corners of such tank, the water in said ltllllt, at its highest level, will not reach the slot '7 :I ljm't'lll to which the tulm 8 is pivotwt this living obviously necessary in order to prevent the contents of the vessel i [From bring; (illlilml with water en tcriug tlurough l'llu slot i'. The outwardly exlit) tending end 8 of the discharge tube will normally overbalance the inner end of said tube, but it will be sustained in an elevated osition, as shown in Figs. 1 and 3 in full IDES, by the action of the float 17 which latter is submerged in the water contained in the flushing tank. When the flushing tank is operated to discharge the water contained therein, the float 17 descends, and the discharge pipe or tube will be tilted until it assumes the position shown in dotted lines in Fig. 1; a charge of the disinfectant liquid which has been previously placed in the vessel 1 will thus be discharged directly into the flushing tank where it min les with the water contained in said tank an passes with said water to the pipes that are to be flushed. As the water in the flushing tank is restored to its normal level, the float 1.7 will rise, and

the discharge pipe will be returned to its normal or initial position, with the $000 12 submer ed in the disinfecting liquid which enters t rough the aperture 14, thus charging the tube 4 for a repetition of the operation.

The improved apparatus is extremely simple in construction, and it may be readily mounted in position for operation upon a flushing tank of ordinary construction; the

improved apparatus bein entirely automatic in its operation, an independent of the mechanism of the flushing tank, except to this extent that the float whereby the dlscharge tube is actuated, is operated by the water contained in the flushing tank. The device may be manufactured and placed upon the market at a moderate expense, and 1t is thoroughly useful and efficient for the pur- I pose for which it is provided.

Having thus described the invention, what I claim is:

- A structure of the character described
